A big thank you to all of you who sent in your photos for our photo competition on the theme ‘Spring at CERN’. We really ...

An amplitude analysis of the charmless three-body decay $B^+ \to K^+ \pi^+ \pi^-$ is presented, based on $pp$ collision data recorded with the LHCb detector at $\sqrt ...

Beyond 25 by ’25 Following the successful conclusion of “25 by ’25” at the end of 2025, the Diversity & Inclusion (“D&I”) Programme is now building on this momentum by launching a new D&I initiative ...

The LHC has successfully reached its nominal Run 3 performance, marking an important milestone in the 2026 physics programme.

For its 2026 edition, Beamline for Schools (BL4S) has received 712 submissions, involving 4051 students from 89 countries, the highest number of applications since its creation in 2014. This ...
